Kramer-
Not to restate the obvious, but something is fundamentally wrong and not lined up properly. The good news is it should be a simple fix.

If your sidepipes are hitting the top of the body cutout on the passenger side, doing the modification to the motor mount or using the torque strap will not solve the problem. From the perspective of sitting in the driver's seat, the motor will want to rotate in a clockwise direction, which will tend to cause the driver's side sidepipe to hit the top of the body cutout, but should push the passenger's side sidepipe towards the bottom of the body cut out, not the top.

If your passenger side sidepipes are hitting the top of the cutout for the bodywork, this is proof that there is likely something very basic and fundamentally wrong. As someone said, lift the motor and reposition it in the mounts, make sure you are using the correct primaries on the correct side of the car and you should be all set.
